In the above structure, you can see that the central atom (tellurium) forms an octet. They mix to give a hybrid that is more than the sum of its components. 1. And then the new hybrid orbitals are formed with six bromine atoms. So now, you have to complete the octet on these bromine atoms (because bromine requires 8 electrons to have a complete outer shell). Jay is an educator and has helped more than 100,000 students in their studies by providing simple and easy explanations on different science-related topics. Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al. As a result, their physical and chemical properties differ dramatically. This . With two bonding pairs and two lone pairs, the oxygen atom has now completed its octet.
